For the production of cement or cementitious materials, any type of blast-furnace slag can be used, but the most common is granulated or glassy slag due to its ease in handling and more rapid reactions between the glass and other raw materials [7]. As cement is hydrated, calcium silicate hydrates (C-S-H) and calcium hydroxide (C-H) form.
Blast-Furnace Slag Cement: Properties There are several properties of Blast furnace Slag Cement that distinguish this cement type from other generic types of cement. The properties of blast furnace slag cement are as follows, The density of slag cement is 3.04 g/cm³. Slag cement has a surface area of 4050 cm²

The various types of slag cements produced are Portland blast furnace slag, Eisen Portland cement, Hochofen cement, Cimetanlaiter. et aux Cenacles, super sulphated cement, and Cimet de laiter a La Chaise. Cu-Zn and Pb slags are also used in cement manufacturing (Bijen Citation 1996; Zhang, Hama, and Na Citation 2015). In …
Cement is produced from suitable raw materials in six stages ( Figure 1 ). Mining limestone/raw materials; grinding, homogenisation, and blending various raw mix components; the preheater phase; processing and pyro processing in the kiln; clinkerizing; and grinding, packing, and transporting materials (Hewlett 2003; Peray and Waddell 1986 ).
Various types of slag are produced: - Blast-furnace slag—The nonmetallic product, consisting essentially of silicates and aluminosilicates of calcium and of other bases, that is developed in a molten condition simultaneously with iron in a blast furnace.
Blast furnace slag (BFS) is a by-product from iron production in blast furnaces, which are fed by a mixture of iron-ore, coke and limestone. In the process, the iron ore is reduced to iron while all remaining materials form the slag, which is tapped off as a molten liquid and cooled.
Blast-furnace slag is used in making-four classes of cement— Puzzolan, or ordinary slag cement, usually simply called slag cement. Slag Portland cement, which may be a true Portland cement. …
